When researching my mother`s side of the family I found her parents belonged to the Primitive Methodists. I had never heard of them and I went on Wikipedia. They have a good general history of this.I got the idea that they were very strict and a "Happy Clappy" religion that would set up a meeting anywhere,anytime they felt. How true this is,I don`t know.When my grandfather died he had moved on to become a very well respected Welsh Baptist!More research I think?! Hope the Wikipedia link may help,
